Mackay in Conn.

I am looking for Alice Elizabeth and Ella(or Ellin)Mackay inCT, possibly around the New Haven area. There was also a Laura who could have been a sister or sister-in-law. Do you know anything about this family? I am so anxious to get beyond this brick wall. Mom spelled her name Mackay-but it could be Mackey in records. Thanks for help.Betty in CA.
